In a closed system, the principle of conservation of mass applies, meaning that the total mass of the reactants is equal to the total mass of the products.
To find the mass of the product formed by the chemical reaction, you can simply add the masses of the two reactants:
Mass of Reactant 1 = 4.0 grams
Mass of Reactant 2 = 12.5 grams
Total mass of reactants = Mass of Reactant 1 + Mass of Reactant 2
Total mass of reactants = 4.0 g + 12.5 g = 16.5 grams
Therefore, the mass of the product formed is **16.5 grams**.
So the correct answer is **C. 16.5**.
